NCIt synonyms : ATP Binding Cassette Transporter; ABC Transport Protein; ABC Transporter Protein; ATP-Binding Cassette Transporter;
NCIt definition : A family of transmembrane proteins that usually function as dimers to hydrolyze ATP,
which permits them to transport a wide variety of substrates across cellular membranes.
These proteins consist of two distinct domains, a transmembrane domain and a nucleotide-binding
domain. ATP binding is required for both dimerization and transporter activity.;
